STEAM NAVIGATION. 



Messrs. Reiiiiie are fitting tlieir trapc/.oidal paddle-wheel to the African, 

 a government steamer, instead of the common paddle-wheel, which has been 

 heretofore used ; this will fonn an excellent criterion of the comparative 

 advantages of the two wheels. They are also fitting similar wliecls to a 

 vessel for the French government. 



The Screw government have determined upon building a steamer for the 

 purpose of trying the .\rehimedean screw ; orders have been given to Messrs. 

 Seaward for a pair of engines of 200 horse power each, for working the 

 vessel. 



A Graeesend steamer is on the stocks, which is stated will run from the 

 lilackwall Railway to (jravesend within the hour. Messrs. Miller & Raven- 

 hill have the construction of the engines in hand. 



Rotary Eiujinex. — Mr. Galloway is about a)>plying a rotary engine of his 

 invention to a new boat, for the purpose of working the screw without the 

 necessity of using any intermediate wheels or gearing. The boiler is tubular, 

 upon the locomotive principle. Messrs. Kennic are constructing the engines, 

 which are now being put on hoard at their wharf at lihickfriars. — Another 

 boat is being fitted with Biniis' patent rotary engines, of considerable power, 

 and a tubular boiler, to work a wheel upon a new principle in the stern ; tlie 

 paddle-hoards are suspended upon their axes, and allowed to work fi-eely 

 upon them without any stops, so that the paddle-board is always kept in a 

 perpendicular position. 



Launch of an Iron Steamer. — There was launched from ilr. Borrie's ship- 

 building yard, IJroughty Ferry, on Friday, 11th ult., an iron-built twin 

 steamer, named the Princess Royal. This vessel has been built for the Tay 

 Ferry Trustees, and is intended to ply between Dundee and Newport ; her 

 length on deck is 1 06 feet, by 34 feet in breadth, giving the extraordinary 

 area on deck of 3604 square feet ; she has been brought up to Dundee, and 

 Mr. liorrie has commenced erecting her engines on board, which are of 80 

 horse power, and one in each of the hulls. The hulls are connected by the 

 deck beams, and by six systems of transverse stays ; the fastenings of these 

 stays are placed within a few inches of the lead water line, for the more 

 effectually maintaining the hulls in their tnie relative position ; there is an 

 intermediate space between the hulls, IO4 feet in breadth, which extends the 

 whole length of the vessel ; there is only one paddle-wheel, and it works in 

 this space nearh at the centre of the vessel, and is com])letely hid from view. 

 When used as a ferry boat a twin steamer possesses many advantages, from 

 her peculiar construction, over a single vessel ; among these the most pro- 

 minent are the great facility with which a twin steamer can take the quays 

 from the absence of the paddle-wheels on the sides, great stability, easy mo- 

 tion in a cross-swell, great buoyancy, without having a great length and 

 breadth of floors, and the sectional area of displacement not greater than 

 what woidd obtain in a single vessel of the usual proportions. The form and 

 finishing of this vessel are much admired, and will not fail to bring additional 

 reputation to the contractor, whose eminence as an engineer is already fully 

 acknowledged.
